Synaptic responses of interbarrelette cells to stimulation of TrV. A: stimulation of TrV evokes a long-lasting EPSP and a small IPSP that has reversed at −90 mV. The membrane potential is held at either −50 mV to increase IPSP amplitude or at −90 mV to reverse the IPSP. B: IPSPs at different membrane potentials are blocked by application of bicuculline (10 μM, 1 vs. 2). C: the late component of the EPSP induced by either weak (top trace) or strong (bottom trace) stimulation, is blocked by additional application of d-APV (50 μM, 1 vs. 2). D: a progressive increase in stimulus intensity (from 0.05 to 0.9 mA) produces a stepwise increase in EPSP amplitude suggesting that interbarrelette cells receive excitatory inputs from several whiskers.
